What happens to the fat we take in meals? When we eat fat, it is digested and absorbed in our gastrointestinal tract. Some fat is not absorbed and excreted. Fat is one of the three macronutrients of human food, along with carbohydrates and proteins. Fat is a very good source of energy and essential for cell formation and vitamin absorption. It is vital for good health. However, an excess of fat is hazardous for our health. Let us delve into the fate of fat in our body. Digestion of fat: Lipids are large molecules, and unlike carbohydrates and proteins, they are not soluble in water and do not mix with the watery blood. So, they like to cluster together in large droplets in a liquid surrounding the gastrointestinal tract. The digestive process breaks those large droplets of fat into smaller droplets, and then enzymes digest lipid molecules using enzymes called lipase. In the mouth: Chewing breaks food into smaller particles and mixes them with saliva. Lingual lipase be

Introduction: The innermost layer of the wall in the gastrointestinal tract is the mucosal membrane. It is worth remembering that the gastrointestinal tract comprises four layers from outside to inside: the serous layer, muscular layer, submucosa, and mucous layer. The mucosal membrane has three layers: 1. Epithelium, 2. Lamina propria, and 3. Muscularis mucosa from inside to outside.
